Comment Feed for Channel 9 - Rob Short (and kernel team) - Going deep inside Windows Vista's kernel architecturehttp://video.ch9.ms/ch9/fdc7/70f4d262-2a53-4719-8f66-91ac75aafdc7/Rob-Short-and-kernel-team-Going-deep-inside-Windo_100.jpgChannel 9 - Rob Short (and kernel team) - Going deep inside Windows Vista's kernel architectureRob Short is the corporate vice president in charge of the team that architects the foundation of Windows Vista. This is a fascinating conversation with the kernel architecture team. It's our Christmas present to all of the Niners out there who've stuck
with us day after day.This is a very candid interview. We even ask &quot;do you ever wish the registry had never been developed?&quot; Charles Torre does this &quot;going deep&quot; interview. Out of all the interviews we've done this one is the most interesting because this team has such a deep impact
on how reliable, scalable, secure, etc Windows Vista actually will be.In this video you'll meet:Darryl Havens, Architect.Richard B. Ward, Architect.Rich Neves, Architect.Enjoy! And, don't be suprised if your brain hurt the way ours hurt after having this conversation.enSun, 02 Aug 2015 20:57:23 GMTSun, 02 Aug 2015 20:57:23 GMTRev9Re: Rob Short (and kernel team) - Going deep inside Windows Vista's kernel architectureLooking forward to this one, hooray for your blog scoble.

http://channel9.msdn.com/ctpmadness/ and also that software has to be installed or uninstalled in a specific order or it leaves the system in a bad state. For example I had a hard time getting CSharp Express 2005 Beta 2 off my system.
I know it should not be installed on a production machine, yada yada, it's a beta, yada yada. But why must it effect, or should I be so bold as say infect, my system like that?

Good lighting in this video. I hope every video has the same level of lighting as much as possible. I hate dark videos where you can barely see the person. Channel 9 needs to invest in some semi-pro lighting equipment. I know this goes against the philosophy
of not being intimidating for the interviewee, but it will go a long way in making videos more clear.

Sorry, there's a lot of reasons why I will never use lights or professional microphones. It comes down to access and having a real conversation. I'm getting conversations no one else has gotten. Why? Because of access and because I don't make people feel uncomfortable.

Have you been in a TV studio with lights or have to put on a microphone? I have. It makes you very aware that you're being filmed. It makes you behave differently than you might if you just were meeting for lunch with some friends. It makes you less comfortable.
(Not to mention that having to mike up four people like in this video is just impossible unless you have an audio crew along and then we're not doing a spontaneous one-hour meeting, we're doing something different.

I also need to be able to walk in, setup, and start shooting. Why? Because that makes it far more possible to get access to these types of people (and to conference rooms -- you did notice that at the end of this one we got kicked out of the conference room,
right? These things are booked around the clock by teams). The more I have to setup equipment, the more time I'll need (I can't walk across campus with much heavy equipment, for instance -- it's already hard enough to get around campus with a 15lb tripod).

I try to get good lighting, but am stuck with what's there. Sorry about that, but my first priority is the conversation.

Fair enough, it's your call and I can understand not wanting to carry equipment around all day long. Though I would suggest using well lit rooms like this one as much as possible when you gather folks for a group interview.

First time posting on Ch9, been watching your videos for a while and I really enjoy them. This has been a real PR coup for MS, even if very subtle.

Where the guy was talking about them having the tech to find dependencies for binaries I thought they already had that. Thats what Depends(Start->Run->Depends (May need Visual Studio installed, I cannot remember where its actually located...)) does.

That doesn't quite do the job in Windows, from what I'm told. What they need to know are the TEAMS who are affected by those dependencies.

Unfortunately I have very little control over where shooting will happen. That's all scheduled by the people I'm shooting. I don't think I've shot in the same place twice.

I would like to see more information about what is happening to make creating shell extensions and namespace extensions easier. It seems to be black magic to get them coded and debugged.

I have made a couple and even though I have plenty of ideas about what I would like to do, it is a pain in the neck to make them.

I only bring this up because one of the guys mentioned that there are some people looking into this af far as extensibility is concerned.

As for cleaning up the registry I'd say thats
an excellent idea - I hope the registry wasn't missed in the LUA guidelines; natrually that should facilitate a large portion of the cleanup.

From the singularity video and this one I'm left with one question: Has the WHQL coming up with more strict criteria for kernel space drivers, specifically video cards? It seems video card and motherboard drivers are going to be the only drivers that will never
be able to touch user space due to latency concerns.

PS: I look forward to hearing from Anders Vinberg about aoughtness and isness.

VDDM display drivers run in user mode in Vista. There is a kernel mode miniport as well, but the main driver runs in user mode. Some of the things they talked about RE: recovery from driver crashes applies here. In Vista, if a display driver faults, Windows
can reload the driver or swap it with a different driver without having to reboot. Driver upgrades can also be handled w/o a reboot. During the upgrade, Windows unloads the current IHV driver, reverts to the standard VGA driver, then loads in the new IHV driver.

Probably the December CTP or Intel/Realtek drivers still need some work in the less glitching audio area since just watching this video (from HDD) had many moments where the audio went into continous glitch for second or two and video halted and resumed
after few seconds. In background I was installing the Beta Client, but XP would not have had any glitches at this kind of little stress test. The hardware is intel 915G with Realtek ac97 audio. Maybe the eye candy is too much for the onboard Intel graphics
solution and thus glitches. The audio is also crackling in the video, but restarting it removed the crackling.

- "overused is the wrong word for the registry. The real problem with the regsitry is that we never actually defined the set of guidelines and schema for how people should use the registry - and if we had done that, we wouldn't be in this mess today."

- "I don't regret the registry was developed; It's unfortunate that the registry was overused"- "overused is the wrong word for the registry. The real problem with the regsitry is that we never actually defined the set of guidelines and schema for how people should use the registry - and if we had done that, we wouldn't be in this mess today."

Do ask why the registry was overused.As I know, Windows Users(not professional developers, or power users) dislike touch the registry at first, but the registry is designed that 1)Windows depend on it too much, and 2)'terrorists' are easy to write a piece of code or javasicrpt(through IE) to affect
the use of Windows, at final, the Windows Users have to google 'the register' for get relative knowledge about the register.The same thing is , you guys write an application(windows) with a Button(the registry), and you tell your customers DONOT click the Button(the registry), because it may damage the application(windows), that's ridiculous.

I personal think the register is more like DOS(or win98...), it's a good idea(or good product) at its time, but now, I have to say it's out of date.

I agree /w Rich Neves towards the end of the tape. The future wont be the "one-size-fits-all"-OS/Kernel. Listening to these "Biggies" gives me a glimpse of how painfull it must be to go through the code and "componentize" the system. It must be a "pain-in-the-youknowwhat"
re-designing/refining this extremly complicated and complex code-snippets. I can only guess...

A lot of things that were discussed (virtualization,usermode-device-driver-framework, fragmentation, memory_management) reminded me of the discussions I follow with the linux-kernel-newsgroup (- no flaming intended).

The "Do you guys wish (that) the Registry would have never been developed?" was sure a fun question which led to some serious answers. Thats what I like.

Unfortunately I had some difficulty to understand what Richard Ward was saying. I guess I was not the only one.

Then use message passing (channels) between all sips. Now that would truly be some
seperate black boxes with effectively *one input queue as the single "API" for each SIP and the Contract becomes the *messages. The apis become private implementation details inside each sip. Not sure if parsing messages becomes the perf killer or if that
can be (or has been) sorted out. That would be interesting.

What was the Obfuscator in the kernel thing? Have a vid scheduled on that? Thanks again!--wjs

VDDM display drivers run in user mode in Vista. There is a kernel mode miniport as well, but the main driver runs in user mode.

I was reviewing the topic and found http://channel9.msdn.com/ShowPost.aspx?PostID=62083 which seems to say that actually the video card driver can't be moved out of the kernel address space yet... I'd like some clarification
but maybe a forum thread would be a better place to persue it.

I have a urgent request for the Vista team. Please, please, please include a checkbox near the start of the setup process that will allow users to opt-out of being protected from themselves. Yes, I understand that user ignorance has been at the core of the
black eye Microsoft has gotten over security. Yet, not all users are idiots. If you were only allowed to eat when my computers caught a virus or malware, you’d be dust by now!
It has only happened twice, and I’m 49.

What I’m really saying, of course, is that Vista–and its setup–must allow for differing levels of user competency. I love XP, but I can’t begin to tell you how many times it has hobbled me as I tried to complete a legitimate task. For my own usage, I need
less security interference, not more.

Where the guy was talking about them having the tech to find dependencies for binaries I thought they already had that. Thats what Depends(Start->Run->Depends (May need Visual Studio installed, I cannot remember where its actually located...)) does.

Depends doesn't work - consider COM and LoadLibrary. These also introduce dependencies but can't be tracked by depends. Also consider RPC interfaces - an RPC client depends on its server.

These guys have some amazing static analysis tools, when they caught one of my dependencies, I was amazed - I hadn't even realized they would find that dependency.

It really seems like windows is broken. From the pervasiveness of the registry to the lack of modularity and isolation - the kernel seems to be a jumbled mess. On a plus note, it is great to see that they are starting the discipline of component isolation.
The question is how deepley coupled these components are? Would it just make more sense to build an entire new system? Or does it make more sense to iteratively partition the system along componet lines? Or maybe Singularity is the savior. Great video!
